Original application led January 12, 1922, SerialNo. 528,651, now Patent No. 1,455,694, dated Hay 15,

1923. `Divided and this application filed October 31, 1922. Serial No. 598,095.v

This invention relates to new and useful improvementsjin car door devices and isaI division of my application filed on January 12, 1922, entitled car door locking devices, and bearin Serial No. 528,651 now Patent 1,455,694 o Ma 5, .1923.

One of the o jects of the present invention is to provide la carl door with an economical form and arrangement of supporting. arms aording a very sturdy construction wherein the material will be utilized to obtain the maximum results with the least expenditure of metal. Another object of the present invention is to provide a' construction for drop bottom doors of freight cars which will not only brace the doors,but, atA the same time, will provide a means whereby the-doors 'may be well supported and firmly held in closed position.

A further object of the present invention is to provide supporting armsy which are attached to the under surface ofthe door and are ofset near theirouter ends, at which points strengthening members in lthe form of brackets' are inserted. To avoid undesirable weakening of the car structure it is necessary that these arms be offsetl as Ythey must extend outwardly beyond the side sill of the car so that they may be readily ngaged by hooks or other forms of support- `ing and locking mechanisms.

Still another object of the invention is to provide supporting arms which. may be formed of conventional angle irons varranged with their upfer legs extertdingfin opposite directions to orm seats respectively adapted to be engaged by the supporting hooks or other devices which 'are used for this purose. 1

`With these and. other objects in view,'the 'invention consists in certain novel arrange.- ments and lcombinations of parts as will be hereinafter more fully described and pointed out in 'the'elaims Referring now to the drawings showing a preferred `embodiment of my invention- Figure l is a diagrammaticview of a Y freight car showing the supporting arms and the hooks engaging the same as applied to two of the doors. y

Figure 2 is a view in elevation of a fragmentary portion of a car side showing the relative position of the supporting arms and the-hooks when the doors are in closed position. n l

Figure 3 is a detail sectional' View taken on 1ine'3-3 of Fig. 2 looking in the direction of the arrows. v i i 'L Figure 4 isV a fragmentary view showing a portion of the door and a supporting arm,

the door being supported in a temporary or l partly I'closed position. A

Figure 5 is a fragmentary sectional view taken on line 5f-5- of Fig. 4 and showing a lever position for forcing the' door to a closed position. v

vThe drawings show the side of a' car l', having the usual uprights or braces 2, a side sill 3, a portion 4 of the Hoor and a door 5. In the present embodiment of the invention '-it will be vnoticed that the floor is cut awa as at 6 andy the door 5 is located beneat said opening and beneath the level of the iioor.

Riveted tov thel center sill 7 of the car is a bracket 8 to which the door-is hinged, a n

leg ot the hinge being preferably secured to 'the door 5 through one 'end of the support- `ing arm 9 which will be described later more `in detail. f

It to bel` understood that preferably there will be two supporting arms foreach door and' naturally two brackets and sets of hinges. .x

4These supporting arms 9' are preferably formed of angle iron and are bolted to the bottom of the door.l They Preferably eX- tend from the rear or' hinged edge of the `door nearly to thefree edge thereof remote from the hinges, and -at their outer ends A,are provided with extensions or short arms 10 which are preferably somewhat heavier per foot than t-he arms `9. Thev corresponding arms 9 and 10i are rigidly connected, prefer'- ably by means' of rivets as shown. The eX- tensions 10 are offset with respect to the .major portions of th4 arms 9 and extend outwardly parallelwith the door, as clearly shown at- 11 in Fig. 3, their length being such that they project beyond the free edge of the door and beyond the outer plane of the side sill 3, thus providing ledges for hooks 12 or other suitable locking mechanisms which may be mounted upon the side of the car for cooperation therewith. The portions of the arms 9 and 10 through which the parallel portions of said arms are connected preferably slope or inclinel downupper le wardly door.

Extending transversely of the door and and outwardly from theplane of the secured lto the bottom or outer ace thereofl near the free edge remote from the Vhinges is a stilfeningbeam or reinforcing member which is preferably in the form of the channel V14, the lower leg of said channel being in contact with and riveted to the respective top legs or flanges of the short arms `10, its

door, an its intermediate portionv constituting a stiening web extending outwardl from the outer face of the door. The c annel 14, it will be perceived, serves as' a reinforcing member for the reeedge of the door and, as will hereinafter appear, providesa seat spaced from the outer face of the door for cooperating with the innerend of a removable lever 18 for forcing the door to closed position. The channel 14 also acts to space the door arms as well as to aiord seats orabutments lor receiving the of the arms 10, thus bracing the door near its opposite sidesand also bracing the supporting arms 9 and 10. lt is to be understood that it is preferable to employ arms '9 with short arms 10 riveted thereto, although, of course,'two long continuous arms odset as shown might be used if desired.

The construction described provides an economical and rigid structure as the supporting arms not only afford conveniently located ledges for cooperating with locking members movabl mounted on the side 'oty the car, but are rigidly held and strengthened by the employment of the brackets 16 l y and the channel 14. I 60.

The lower edgeA of the side of the car which is embodied in the channel 3 lies bef low the plane ot the car door 4 and below the plane of the door 5. As the door-supporting hooks 12 which are movably mounted upon a stationary part of the car are preferably pivoted upon the side sill 3, the outer ends 11 ol the door arms 10 are spaced away from the bottom or outer lace of the door so that they mah extend outwardly beneath the side sill ot the car to a point beyond the outer plane thereof enabling them to engage the shoulders or ledges or" the hooks. lt is desirable in such a construction that the spaced ends of these arms 10 should be stillened and tied to the door in a manbeing rigidly connected to the' in their-correct positions.

.en and brace the channel 14, while thelat-y ositer in "turnholds the braces in their tions at right angles tothe free edge 0 the door` and braces the outer ends of the airms 10 against movement lengthwise of the door.

lt will thus be seen that these several members support "and brace each other so as to strengthen the door and maintain all parts lt will also be appreciated that by arranging the door arm to seat beneath the spacing and reinforcing channel member 14 between'the extremities of the arm, and by securing the inner eX- tremity of the arm to the door, as for example by means of the gusset 16, the reinforcling arm member 9 and the rivets used there' with, he metal of the door arm is utilized.

tothe best advantage and the stress therein incident to supporting the loaded door at the outer end of the'arm will be minimized.

'llhe -hook 12 preferably seats beneath one leg' only of the an le iron and the weight of the loaded door t erefore is transmitted to the hook through this leg alone. ln order that both legs of this angle iron arm 10 may be utilized' for resistance at the point of greatest stress in the arm, it is preferable that both legs of the angle should be suitably secured tothe door. l1" or this purpose a rivet is emp oyed for attaching the horizontal leg ofthis' angle to the bottom ange ofthe channel 14,' which latter is in turn secured to the door by means of bolts, while other rivets rmly connect' the vertical leg of this angle to the gusset 16which is secured to the door and also to the channel 14.

By positioning the'side sill channel 3 with its flanges extendin inwardly the hook 12 may be arranged c ose to the plane of the outer face or side wall ot the car, thus re-v ducing the over-all width of the car and providing a construction that is unlikely. to

become inoperative through bending or warping of parts. The hook engaging Hanges or legs of the supporting arms 10 of each door preferably extendin opposite directions from the vertical legsofthe said r arms, so thatwhen they are engaged by the oppositely facing hooks 12 or other preterable supporting means any tendency oit the door to shift longitudinally of the car will be overcome; but this latter feature is the subject of another one of my pending applications.

A recessed tulcrum member, which may advantageously be formed as an apertured plate 17, is preferably fastened to the car side midway between the supporting arms izo ' tothe car body and lying above the vbot-4A 10. By passing a removable'-lever, suchas 18, through the aperture in the plate the inner end `of said lever may be caused to scat against the lower part or flange of the channel 14 adjacent either of the arms 10, thus enabling the door to be readily forced to a closed positio'n.' This fulcrum construction .in its broad aspect forms the subject matter of the original applicationof.which this is a division.

From the foregoing itwill be perceived that l have provided a construction whereby, the door is greatly strengthened and braced throughout `and by which convenient means 'are provided for constituting ledges suitable for' engagement by any desirable form ofdoor supporting and lockingmechanism mounted on the side of the car.

Many slight changesv might be made in the construction without departing from the spirit and scope of my invention.
